I'm trying to solve vast system of differential equations (Hamiltonian equations of motions).
I have this kind of error and don't know what to do with it:
Error, (in dsolve) found the independent variables {t} also present in the names of the functions of the system {(cos(varphi(t)))((3333333333/10000000000)/sin(theta(t))^2+(1/23)*cot(theta(t))^2/R(t)^2), (sin(psi(t)))((3333333333/10000000000)/sin(theta(t))^2+(1/23)*cot(theta(t))^2/R(t)^2)}
